NettetContact metamorphism creates no-foliated metamorphic rocks. Magma will bake the surrounding rocks due to difference in temperature. Deformed rocks with foliation/lineation are brought by pressure and recrystallization of minerals. Pressure is the main factor of contact metamorphism Slate and gneiss are examples of foliated rocks. 9. Let’s do it! NettetMetamorphic texture can be foliated or nonfoliated.

The word “foliation” comes from the Latin word folium, meaning “leaf”. The foliation process may occur during the rock’s formation, or it may be the result of metamorphism … NettetThe texture of metamorphic rocks can vary from almost homogeneous, or nonfoliated, to foliated rocks with a strong planar fabric or foliation produced by alignment of minerals during recrystallization or by reorientation. Common foliated metamorphic rocks include gneiss, schist and slate. Marble, or metamorphosed limestone, can be foliated or ... hdf titan
